As one of the crucial procedures of shield boring, the arriving of shield machines with superlarge diameters is complicated in technology and has great risks. Taking the arriving of the shield machine for Nanjing Yangtze River Tunnel as an example, the author presents the comprehensive construction measures, including the portal section reinforcement by mixing piles, dewatering, freezing and water & soil filling in shield arriving shaft. The above measures guarantee the safe arriving of the superlarge diameter slurry shield under the condition of shallow cover and highly permeable ground. This paper can provide reference for similar projects in the future.
